Casio fx-CG50: Animation of a Graph

Casio fx-CG50: Animation of a Graph

Introduction

You can easily animate a graph with the Dynamic Graphing mode. While I'm describing this procedure for the fx-CG50, I'm pretty sure it is available for the earlier models such as fx-CG10, fx-9750GII, and fx-9860GII.

Specifically, you can dynamically change a single variable between two points with a specified step.

For example: y = A*x where A varies from 0 to 5, and its step is 1.

General Procedure

1. Enter Dynamic Graph mode. On the fx-CG50, press [ MENU ], [ 6 ].

2. Type and select an equation. The equation can be a function, a set of parametric equations, a polar equation, or on newer calculators, a shaded inequality.

3. Press [ F4 ] (VAR) to take you to the variable screen. Select the variable you want to animate. You can animate any variable A - Z and θ. Keep in mind that X is used for functions equations, T is used for parametric equations, and θ is for polar equations.

4. Set the Animation Speed by pressing [ F3 ] (SPEED). The speeds that can be selected are:
